This is probably a basic question, but I was wondering if / how it's
possible to run a find on an existing hash.
For instance:
1. I need to pull all products in the database for a simple list:
@products = Products.find(:all)
2. At a separate portion of the page, I want to display products that
are in, say, category 5.
>From scratch, I could run...
@new_products = Products.find(:all, :conditions => {:category_id => 5})
Although, I thought you could also do
@new_products = @products.find(:all, :conditions => {:category_id = 2})
My query has been returning a wrong number of arguments (2 for 1), so I
wasn't sure if I was headed on the right track.
